Today is the anniversary of the First Fleet’s arrival in Sydney Cove, only 228 years ago. A defining moment, certainly, although more and more people agree that the 26th of January is not the right day to honour all things Australian.
To commemorate the date, let’s have a look at Australia’s earliest weather observations. Their history, funnily enough, began at exactly the same time…Read More »
Wearing bathers around the house, sleeping in the living room under the fan, covering windows with wet towels, giving up on the balcony plants, staying at work until late because that’s where the AC is, eating watermelon for dinner kind of hot.
The temperature in Tortosa has not dropped below 20º since the 26th of June, and maximum temperatures are ranging between 30 and 39ºC. It’s these high minimum temperatures that can be the real killer, particularly for the elderly and vulnerable who do not have access to AC.
I was going to try and write about the science of this crazy heat, but a) my computer (and myself) do not work well in high temperatures and b) this article from The Conversation explains what is going on, with neat pictures too.
Essentially a high-pressure system has parked itself over western Europe, suppressing clouds and diverting any low pressure system that might want to meander this way. It is also being fed warm air from the south thanks to high pressure in the upper parts of the atmosphere. Just read the article, they explain it much better.
In Australia, heatwaves occur in a similar way, when the jet stream and a surface high pressure system push warm air down from the middle of the country. However in Europe, the warm air comes up from Africa, instead of down from the red centre.
One interesting part of that article that I was not aware of is the Spanish Plume. The warm air travels up from Africa, over the Iberian Peninsula where it gets even hotter and drier. From there it ends up near the UK, where it meets cooler air coming down from the north. This results in some terrific thunderstorms.
We were lucky enough to experience both the middle and the edge of the giant pillow of hot air this week. For the first half of the week we melted in our non-air-conditioned apartment, eating ice cream and trying to think of cold things.
In the second half we were in Ireland for the wedding of some lovely friends. I’ve never been so happy to wear a scarf! Western Ireland was brisk and showery, which may be characteristic of the Atlantic climate, and on our return to Dublin we saw some ripper cumulonimbus clouds which I now realise may have been the edge of the warm air. We even went through a town that had completely lost power thanks to the storms.
Now we are back in the heat, daydreaming about green fields and trying to keep cool. There is no respite in sight, with the Spanish Meteorological Agency predicting similar temperatures for at least the next week. Please look after yourself Tortosins, and your neighbours. See you at the beach.
Despite the fact that my job is all about the atmosphere, the one thing that is guaranteed to ruin my day is wind. Not passing wind, that’s hilarious, but unrelenting, tree-bending, dust-blowing, hair-mussing wind that come from air migrating from one spot to another.Read More »
My PhD was on the past climate of southeastern Australia. This involved looking at lots of different sources of old weather data from the 1800s. Newspapers, government records and farmer’s diaries: each source an important clue to the history of Australia’s climate.
While my work focussed mainly on quantitative data (numbers) rather than qualitative descriptions of what happened (words), using both sources of information can improve our understanding of the weather of the past. Plus, much like music and lyrics (great film), they tell a much better story together.
I want to share some of the more exciting events in the archives of Australia’s weather. Everyone loves talking about the weather, and extreme events, woah! Can we talk about anything else? So let’s start with an easy one. A classic. Sunday 28 June, 1836: snowfall in old Sydney town.Read More »
